Taking a shot in the dark in case anybody here has any brilliant ideas. I inherited what used to be a fairly nice RV (my father paid $20,000 for it shortly before he died). It has sat idle since then and fallen on hard times (mold on the outside, been broken into, probably had a rat or two sleep in it, mild interior water damage).

I don't want to deal with it. Are there any outfits or people that "flip" RVs, or that would give me something for it? Is probably not the sort of thing I can sell through traditional channels due to its shape, but I'd like to get some value out of it.

You can use a consignment lot. If I was you, I'd do the minimum and then sell it. You could try posting an ad here for help, or to sell it. Mold is relatively easy to take off to make it look much better. Mouse traps are also cheap.

I have no idea where you might be located. But, locally, I am aware of a salvor who deals in lots of different salvage, including travel trailers and motor homes. He's a little on the unreliable side as far as getting back to you and as to promptness, And, needless to say, he will want it as cheaply as possible. Send me a PM if you are interested. Don

As jimh suggested you should consider consignment. Take it into an RV dealer and work a deal with them. They will want it looking good while it's on their lot so they will take the time to clean it and you won't have to.
Otherwise clean it yourself and put it in the classifieds, sooner than later as summer time is the best for selling RV's.

Call the local dealerships, they will buy them, and put them on the lot as used units. I remember a few times, at the dealership I worked at, we would buy them.
